SPECIFICATION forming part of Letters Patent No. 716,310, dated December 16, 1902.

Application died December 30, 1901. Serial No. 87,813. (No model held in their engaged position by means of snap-catches, as hereinafter .set forth and claimed.

In the accompanying drawings, Figure 1 `represents a view of the front side of a iiat steel spring-bar provided with my improved engaging hooks. Fig. 2 represents an edge view of the same. Fig. 3 represents a View of the back side of the spring-bar provided with the engaging hooks. Figs. Il and 5 are detail views of thespring-bar, showing different forms of construction. Fig. drepresents an enlarged front view of one of the attaching-hooks for engagement with the fabric of the seam. Fig 7 represents a side view of the same. Fig. 8 represents a rear end View. Fig. 9 represents a front view of the sheetmetal strap for connecting the attachinghook to the spring-bar. Fig.' 10 represents an edge view of the same. Fig. 11 represents a longitudinal section of the seam of the garment, showing the engagement of the attaching-hook therewith. Fig. 12 represents the form of the blank from which the attachinghook is formed.

In the drawings, A represents a fiat springbar, of steel or other suitable material, made of the proper length and thickness and preferably provided at its opposite edges with the notches a a, the said notches being adapted to receive the turned earsb b of the sheetmetal strap B, by means of which the attaching-hook C is secured to the spring-bar A.

The strap B is provided with the projecting studs c c,"1nade integral with the strap, and upon the studs c c is pivoted the attachinghook C, the said hook being first cut out from sheet metal in the form shown in Fig. 12 and then turned to the form` shown in Figs. 6, 7, and 8, the perforations d d being adapted to receive the pivot-studs o c of the strap B, thus pivoting the attachinghook to the spring-bar. The attaching-hook C is also provided with the backwardly-extending ears e e, which being turned inwardly at their ends serve to snap overy the edges of the spring-bar A, and thus hold the hook C in its attaching position. The hooks C C at the opposite ends of the spring-bar A are arranged for engagementin opposite directions, and in Figs. 1, 2, and 3 three of the hooks are shown in the engaged position, while an end hook is shown in its position preparatory to engagement, the position of the hook when fully engaged with the fabric and held at its rear end by snap engagement with the edges of the spring-bar being shown in Fig. 11, in which f represents one of the plies of the seam and f the other, the hook C being turned outward from its position shown at C", Fig. 2, in effecting the required engagement, and when the several hooks are thus engaged with the seam D the spring-bar A will be properly secured to the garment and be capable of ready removal therefrom when desired.

Instead of employing the strap B for effecting the attachment of the hook to the springbar the spring-bar itself may be provided with suitable studs c c, either by soldering a piece of wire across the spring-bar or by forming the studs integral with the spring-bar, as

shown in Fig. 5.

I claim as my invention-- 1. The combination of the spring-bar, a hook pivoted thereto at one of its end portions and adapted for detachable engagement with the fabric at the opposite edges of the springbar, and the snap means for holding the hook in engagement with the fabric, with an oppositely-direoted hook, adapted for engagement with the fabric at the opposite end portion of the spring-bar.

2. The combination of the spring-bar, with the pivoted hooks arranged to turn in opposite directions, for attachment and means for holding the hooks in their engaged positions,

'substantially as described.

3. The combination of the spring-bar provided with the notches at its edge, and the straps engaging with the notches and provided with the studs, with the oppositely-directed hooks pivoted upon the studs of the straps, and means holding the hooks intheir engaged positions, substantiallyas described.
